Overview
CS2844/3845 SERIES CS2844/CS3844 CS2845/CS3845 Current Mode PWM Control Circuit with 50% Max Duty Cycle Description Features The CS3844/45 provides all the necessary features to implement off-line fixed frequency current-mode control with a minimum number of external components.
The CS3844 family incorporates a new precision temperature-controlled oscillator to minimize variations in frequency.
An internal toggle flip-flop, which blanks the output every other clock cycle, limits the duty-cycle range to less than 50%.
An undervoltage lockout ensures that VREF is stabilized before the output stage is enabled.
In the CS2844/CS3844 turn on occurs at 16V and turn off at 10V.
In the CS2845/C...
